Much like the earlier Wapo poll, this poll is HEAVILY weighted towards Dems. There is nearly 34% of the sample that are Dems and just 27% GOP...which isn't quite as absurd as the Wapo's 36-24 gap. All that said, the difference between the candidates is just 6% when all candidates are included. So far from dismissing this poll, I'd support its validity...because what it is really showing is that the race is extremely tight. Were the samples weighted more reasonably you could expect its outcome to show the race within the margin of error....and keep in mind, this is a registered voter poll not a Likely voter one. If it were a LIkely voter poll, the results would be tighter still...perhaps showing a slight Trump advantage.
Worse, the poll is a self-selecting sample meaning sampling error is incalculable...which the pollster acknowledges in his methodology statement.
So we should never dismiss polls like this, but you have to be smart enough to dig down into the methodology and see what the poll is really telling you...and its not telling you what the deceptive headline of the article or this thread asserts. It IS telling you that the presidential race is very tight. The difference, small though it may be, is that a small percentage of Republicans are failing to rally to their nominee...while more Democrats ARE rallying.
So you can directly attribute nearly all of Hillary's lead to the NeverTrump voters...congrats. Most likely you'll be receiving thank you notes from the Hillary campaign when this is all over....and later, from her numerous Supreme Court Appointees.
